I played around for years with power/spell points and even came up with some fun rules for them. But for me, Pathfinder does such a good job with making the spells per day system fun and enjoyable, so I felt the psionics put out by Dreamscarred Press is just unnecessary.
This book however, it expands on the spells per day and the ki pools. It makes them interact much in the way that the Arcana pool for the Magus does. Which is awesome! My only complaint is that it only introduces two new classes to Pathfinder, and I like having a variety of different magic classes for my players to choose from. I wish there were more, but I'm using the rules presented in here to make my own homebrew archetypes, favored class options and alternate racial abilities to truely bring the Power of Ki to life in my campaigns.
